BudsGunShop.com - What is the frame of this gun??

I own a Taurus Model 66 which is basically a copy of this, it's an L-Frame.

This is an L frame made of strong stainless steel

This is an L frame, which uses the same size grips as a K frame.
From small to large it's J,K,L,N,X (someone forgot N). Additionally, the governor series are denoted as a Z frame.
Hope this helps!

It's an "L" frame ....I have two ,....two of my shooting buddies also have 686's. I'm assuming the guys saying "J frame" are making a joke. Hard to imagine anyone one this site could miss this at all ...much less two frame sizes off. FYI....from small to large it's a J,K,L,X . If your talking about the grip frame,...it appears to be a square frame. Although the new 686, 3-5-7 model is a round butt frame. With all the new grip shapes it can be hard to tell the shape of the frame....square or round.

Size is "L" frame. Material is SAE 416 stainless hardened to about 30 HRC.
